INVESTIGATION OF THORIUM SEPARATION FROM VARIOUS ELEMENTS BY TRACER METHOD. I. EXTRACTION OF THORIUM PHENYLACETATE BY DIETHYL ETHER. URANYL ION COMPOUNDS WITH PHENYL ACETIC ACID. SEPARATION OF THORIUM FROM URANIUM (in Russian)
Favorable results were achieved in extractions of thorium phenylacetate by carbon tetrachloride, chloroform, diethyl ether, benzene, toluol, butyl alcohol, methyl butylketone, and other organic solvents. Complete extraction by diethyl ether was obtained at pH 3 to 5 and ammonium chloride ionic strength of 2. Quantitative extraction of thorium from the organic phase is accomplished by reextraction with dilute (1: 10) mineral acids. The dissociation constant of the phenyl acetate is (8.1 plus or minus 0.4) x 10/sup -//sup 5/ and the distribution constant between diethyl ether and water is 34 plus or minus 2 at 20 deg . A double uranyl and ammonium phenylacetate, UO/sub 2/(C/sub 6/H/sub 5/ CH/sub 2/COO)/sub 2/ - C/sub 6/H/sub 5/CH/sub 2/COONH/sub 4/, was found, and a method was developed of separating thorium from larger quantities of uranium through the phenylacetate formation.
